Big Bang Theory: A Brief Explanation

              Big Bang Theory remains the premier scientific theory for the universe’s creation and evolution. It holds that the universe is 13.8 billion years old. Most importantly, it describes the universe as continually expanding. Big Bang Theory remains supported by Hubble’s observation that the farther a galaxy is, the more it appears to be moving away.

               During this process, material evenly exploded from a single point which created the universe we live in today. After this, there was rapid inflation, where the space expanded and cooled at superluminal speeds. Energy got converted into fundamental particles like quarks. These quarks combined to form fundamental particles like neutrons and protons. These particles compose well-known elements like helium. This expansion means that distant galaxies become even more distant over time, decreasing the likelihood of future extraterrestrial contact.

              Gravity acted upon matter which condensed it into dense stars, which used nuclear fusion for energy. This principle of accretion applies to other celestial bodies, where matter pulls together to form larger objects like stars and planets. The decreasing Cosmic Microwave Background radiation temperature provides additional evidence for the Big Bang Theory. Big Bang Theory remains supported by calculations, including nuclear and relativity equations of helium, beryllium, and lithium amounts that match the actual quantities.

             However, the immediate “start” of the Big Bang and antimatter and dark matter interactions remain unexplained in our current Big Bang Theory Model.
